What is your HCS computer login username?
first letter of first name
three numbers (usually 001)
What is your Certiport username?
First Initial (capitalized)
Last Name (capitalized first letter)
Four-digit number like 0904
Example – S.Shultz0904
What is your Certiport password?
Same as user name, BUT
Add a “1” at the end
Example – S.Shultz09041
K = kilo = 1,000 (thousand)
M = mega = 1,000,000 (million)
G = giga = 1,000,000,000 (billion)
T = tera = 1,000,000,000,000 (trillion)
Measured in Hz (hertz)
Means cycles per second
The more cycles it can process, the faster it can run
1a. If a CPU is rated at 500 MHz, how many cycles can it process in a second?
500 times M (1,000,000) =
500,000,000 (500 million)
1b. If a CPU is rated at 1 GHz, how many cycles can it process in a second?
1 times G (1,000,000,000) =
1,000,000,000 (1 billion)
1c. If a CPU is rated at 950 MHz, how many cycles can it process in a second?
950 times M (1,000,000) =
950,000,000 (950 million)
1d. If a CPU is rated at 1.1 GHz, how many cycles can it process in a second?
1.1 times G (1,000,000,000) =
1,100,000,000 (1.1 billion)
1e. Which CPU is faster, one rated at 1.1 GHz, or one rated at 950 MHz?
1.1 GHz = 1,100,000,000
950 MHz = 950,000,000
Hard Drive Capacity
Measured in B (bytes)
Means pieces of data
More bytes on the hard drive = more data you can store
2a. If a hard drive holds 200 GB, how many pieces of data can it store?
200 times G (1,000,000,000) =
200,000,000,000 (200 billion)
2b. If a hard drive holds 1TB, how many pieces of data can it store?
1 times T (1,000,000,000,000) =
1,000,000,000,000 (1 trillion)
2c. If a hard drive holds 750 GB, how many pieces of data can it store?
750 times G (1,000,000,000) =
750,000,000,000 (750 billion)
2d. You need to have a total of 1TB of storage, and you already have a hard drive that holds 750GB. What is the smallest hard drive you can add and have 1TB of storage?
1TB (1,000,000,000,000) minus
750GB (750,000,000,000) =
